Abstract: There is provided an aromatic polycarbonate resin composition exhibiting excellent mechanical strength, transfer property, light transmittance, thermal stability and moldability which is capable of being molded into thin-wall products and large-size products, as well as a light guide plate produced from the resin composition. The present invention relates to an aromatic polycarbonate resin composition for light guide plates, comprising an aromatic polycarbonate resin having a viscosity-average molecular weight of 13,000 to 15,000, and a ratio of a weight-average molecular weight to a number-average molecular weight (Mw/Mn) of 1.5 to 2.7 in terms of polystyrene as measured by gel permeation chromatography; and a stabilizer and a releasing agent blended in the aromatic polycarbonate resin, as well as a light guide plate produced from the resin composition.

Abstract: There is provided an etching liquid composition for a multilayer film containing copper and molybdenum. The etching liquid composition comprises: (A) a peroxosulfate ion source; (B) a copper ion source; and (C) at least one nitrogen compound source selected from the group consisting of ammonia, ammonium ions, amines, and alkyl ammonium ions and has pH 3.5 to 9.

Abstract: The present invention relates to a multilayer laminated product which at least contains a layer formed of an acrylic resin composition containing an acrylic resin as a main component, and a specific terminally-modified polycarbonate resin. Moreover, the multilayer laminated product of the present invention has an excellent releasability and low frictional properties.

Abstract: A method of providing an oxygen barrier for a product includes placing a product in an injection molded article which includes 10 to 60% by mass of a polyamide resin (A) and 40 to 90% by mass of a mixed polyolefin (E), wherein the polyamide resin (A) includes a diamine unit 70 mol % or more of which is one or more m-xylylenediamine units and a dicarboxylic acid unit 70 mol % or more of which is one or more dicarboxylic acid units including a C4 to C20 ?,?-linear aliphatic dicarboxylic acid and isophthalic acid at a molar ratio of from 30:70 to 100:0, the mixed polyolefin (E) includes 40 to 100% by mass of a polyolefin (C) and 0 to 60% by mass of a modified polyolefin (B), and at least a portion of the polyamide resin (A) is dispersed in a layered state.
